    dct:description "60 m EMIT Version 2 methane column enhancement, sensitivity and uncertainty rasters. Granules include scenes without identified plume complexes; a footprint does not identify a confirmed emission source. These are Earth observation retrievals, not weather forecasts or terrain products. Nominal archive bounds do not guarantee valid pixels or continuous observations." ;
